Rage Against the Machine’s Tom Morello is reportedly blasting President Trump for his verbal battle with Bruce Springsteen, accusing the commander in chief of being “mad” at the rocker for being more popular.

“Bruce is going after Trump because Bruce, his whole life, he’s been about truth, justice, democracy, equality,” Morello said Sunday while performing in Boston, according to media reports.

“And Trump is mad at him because Bruce draws a bigger audience. F— that guy!” Morello said.

Video of the performance shows Morello appearing in front of a backdrop featuring a collage of expletives and images of Trump.

The Prophets of Rage guitarist, an outspoken critic of Trump who’s toured with Springsteen, reportedly told the crowd at the concert that it would be the “last big event before they throw us all in jail.”

Morello’s comments came following blistering remarks from Springsteen earlier this month directed at Trump.

The U.S., Springsteen said while launching his concert tour in England, is “currently in the hands of a corrupt, incompetent and treasonous administration.”

Trump slammed the “Born in the USA” singer in a series of social media posts, calling him a “pushy, obnoxious jerk” and sharing a video of him striking the 75-year-old performer with an animated golf ball.

The president later called for a “major investigation” into why some stars, including Springsteen, lined up to support then-Vice President Kamala Harris’s 2024 White House bid.
